In this embodiment, the first accumulated time threshold may be an accumulated high temperature time warning threshold (which may be represented by TSH, and above which the battery is prone to bulge).
In the charging and discharging operation using the battery in the terminal, only the TS value of the battery in the terminal may be considered, that is, the charging and discharging of the terminal may be controlled according to only the TS value of the battery, and it is of course not excluded in the present embodiment that only the TN value of the battery in the terminal is considered, or the TS value of the battery and other temperature parameters are comprehensively considered to control the charging and discharging of the terminal.
The following describes the control of the charging and discharging of the terminal by integrating the TS value and the TN value of the battery:

step S402: and when the first type of battery comprises a battery with TN less than or equal to the continuous time threshold, taking the battery with TN less than or equal to the continuous time threshold as a second type of battery and utilizing the second type of battery to perform charge-discharge operation.
In this embodiment, the continuous time threshold may be a warning value of the continuous high temperature time (which may be expressed by TNH, and the magnitude of the warning value may be flexibly set, for example, may be set to 30 minutes, or to 15 minutes, or to 5 minutes, etc.).
The following description will be made regarding the control of the charge and discharge of the terminal in consideration of only the TN value:

In this embodiment, the second accumulated time threshold may be an accumulated high temperature time general threshold (that is, a value lower than the accumulated high temperature time warning threshold may be represented by TSL, and exceeding the general threshold represents that the accumulated high temperature time of the battery has reached a certain proportion of the warning threshold, and the size of the general threshold may be fixed or may be flexibly adjusted, and the value thereof may be a certain proportion of the accumulated high temperature time warning threshold, for example, may be 50% of the accumulated high temperature time warning threshold, or 30% of the accumulated high temperature time warning threshold, and the like).
In an alternative embodiment, the charging and discharging operations using the third type of battery include: and when the number of the third type batteries is at least two, performing charging and discharging operation by using the third type batteries according to a preset charging and discharging strategy. In this embodiment, the predetermined charge and discharge strategy may be a preset charge and discharge strategy (which may also be referred to as a default charge and discharge strategy, and the charge strategy may be an existing charge and discharge strategy, for example, for a dual-battery terminal, the preset charge and discharge strategy may be that a certain battery is first charged and discharged, and another battery is charged and discharged after the battery is fully charged or after the electric quantity is lower than a predetermined value, and of course, the preset charge and discharge strategy may also be that two batteries are simultaneously charged and discharged, and the like).
In an optional embodiment, before the discharging operation using the third type of battery, the method further comprises: and when the second type of battery is determined to further comprise a battery with TS larger than the second accumulation time threshold, and the electric quantity of the battery larger than the second accumulation time threshold exceeds the electric quantity threshold, discharging the battery larger than the second accumulation time threshold to the electric quantity threshold. The present embodiment is mainly directed to the case of performing a discharging operation by using a circuit in a terminal, and in the present embodiment, if there is a second type battery with a higher electric quantity (i.e., the electric quantity exceeds an electric quantity threshold, for example, when the battery is fully charged), the second type battery with the higher electric quantity can be preferentially used for discharging until the electric quantity is discharged to the electric quantity threshold.
In an alternative embodiment, the discharging operation using the second battery type includes: and when the second type of batteries comprise batteries with TS less than or equal to a second accumulated time threshold and batteries with TS more than the second accumulated time threshold are determined, and the batteries with TS more than the second accumulated time threshold are in a full state, performing discharging operation according to a preset discharging strategy, wherein the second accumulated time threshold is less than the first accumulated time threshold. In this embodiment, the predetermined charging and discharging strategy is also a charging and discharging strategy that is set in advance, and is not described herein again as in the foregoing embodiments.
In an optional embodiment, when it is determined that there is a battery with a TS less than or equal to an accumulation time threshold in the terminal, the method further includes: and prompting that the battery in the terminal is in a long-term overheating state when the battery with the TN less than or equal to the continuous time threshold value is determined not to be included in the first type of batteries. In this embodiment, it is pointed out that TN of the first type battery in the terminal is greater than the continuous time threshold, and in this case, the user is prompted that the first type battery in the terminal is in a long-term overheat state, so that the user can be reminded of needing to perform heat reduction processing on the battery. In this embodiment, there are various prompting manners, for example, a manner of generating a specific prompting sound (for example, sounding an alarm) may be adopted for prompting, a voice prompting may be performed, or a manner of displaying a text may be adopted for prompting.
In an optional embodiment, after prompting that the battery in the terminal is in a long-term overheat state, the method further comprises: limiting charging and discharging of a battery in the terminal; and when the temperature of the battery subjected to the charge and discharge limitation is determined to be reduced to be lower than the preset temperature, performing charge and discharge operation by using the battery subjected to the charge and discharge limitation. In this embodiment, the charging and discharging may be limited in various ways, for example, for the case of charging, the charging current may be reduced to limit, and for the case of discharging the terminal, the low power consumption mode (for example, reducing the screen display brightness) may be turned on to limit.
